## Description

This diesel/electric hot air turbine space heater is suitable for heating ventilated areas, such as construction sites, new buildings or warehouses up to 166m². A 19 litre fuel tank for diesel is used for heating with a consumption of approximately 2 litres per hour. The electronics and fan are powered by mains electric. The maximum air flow is 588m³ and maximum outlet air temperature is 393°C. A built in thermostat enables you to control the temperature. Easy to operate. Once full of diesel and plugged into the mains, just select the desired temperature on the thermostat and turn the power switch to on. The power indicator lamp will light up and the heater will start. Safety features include auto overheat protection, where the heater is cut off should the internal temperature rises to an unsafe level; a circuit breaker protects the electrical system from damage and a flame sensor will detect if the flame is extinguished and will stop the electrical current, shutting off the heater.
